To all who/m may concern: Be it known that I, DANIEL TATUM, 1a

'citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful` Improve'- ments in Construction of Car-Roofs; .and I do hereby declare the following to be a full, clear', and exact description of the in-' vention, such as will enableothers skilled in the art to which it appertains to make and use 4the same, reference beinghad to the accompanying drawings, and'to the figures of reference marked thereon, which form a part of lthis specification.

. 'Ihe invention about to be set forth and claimed belongs to the art of car construc-l tion, and it particularly pertains to a new and novel structure of a car roof, which is designed mainly foruse upon freight cars and the like. y

The essential object of the invention' is the provision of a roof construction for freight cars, provided with means to allow the various parts formingthe structure 'of the roof to have considerable play, for instance, when the car is -subjected to considerablc hard usage.

Another object of the'invcntion is to pro-i vide novel means for supporting the running boards (which are usually carried upon the top or roof of the car) and to provide means for securing the running boards saddles properly in place.

A further object of the invention resides in the provision of a cap, cover or closure to be arranged above the ridge-pole and to extend laterally of the said pole, in orderto cover part of the metal roofing of the car.

A further object of the invention is the provision of means for securing the metal roofing to the sidings and the facias.

I n this specification and the drawings accompanying the same, a certain structure of device is adhered to, but the invention is not to be restricted to this particular structure. The device, in its actual reduction to practice, may require certain changes and variations; the right thereto belongs to the applicant, vprovided such changes and variations are comprehended by the appended claims.

The invention consists of various other objects and combinations of parts which structure of that portion of the car.

' of a casting) will be hereinafter .more clearly set forth and pointed out in the appended claims.

In the drawings:-Figure 1 is a perspective view of the upper portion of a freight car, clearly illustrating the outside appearance of the car. Fig. 2 is a cross sectional view through the car, showing the under structure of the roofing and the dispositions of thevarious parts, for instance, the ridgepole, the facias and the sidings. Fig. 3 is a longitudinal sectional view throughthe top or upper portion ofthe freight car, showing one or more' of the running boards saddles, and the means for securing the running boards and the saddles inv position. Fig. 4 is an enlarged. detail sectional view through the ridge-pole and a portion of -thc roofing, in order to illustrate the detailed Fi 5 is an enlarged detail sectional viev through a portion of the side of `the car, so as' to illustrate upon an enlarged scale the siding and the facia, showing the manner of connecting the roofing thereto. Fig. 6 is an enlarged detail perspective view of a holding member (which may be in theform saddles an the running boards, in order for cooperating between the.

to prevent displacement of the boards. 'F ig.

7 is a perspective view of the cap plate, cover or'closure for the ridge-pole. Fig. 8 is a detail cross-sectional view uponv line S-8 of Fig. 2, in order to disclose the comparatively loose connection between the sections of the metal roofing, and showing the manner in which a portion of the cap'pla'te or cover engages this loose connection. Fig. 9 1s' a detail perspective view of one of the clips and a portion of the outer edges of the metal roofing, in order to disclose how the clips readily engage to hold the metal roofing in place. Fig. 10' is an under face view of one of the holding members.

In regardto the drawings',l 1 denotes the upper portion of a freight car, which consists of a rectangular frame comprising the transverse and longitudinal beams or rafters 2 (upon which the wood tongue-and-grooved roofing 3 is supported) and the vertical and transverse-beams 4 of the sides of the car,

to which the tongue-and-grooved sidings 5 are secured.

Adjacent the upper longitudinal corners -G ofthe car, aciastrips 7 are secured, be-

.Y tween which land the, sidings'a plurality of .blocks 8 are disposed, in order toprovide a angular'cutaway portions 11. The opposite races of the longitudinal raised portion, ad*

jacent to the point where the raised portion merges into the base of theridge-pole, are slightl 4 whichv the adjacent edges of the wood vtongue and-grooved roong contact (which edges of the wood tongue-andegrooved roofing are received within the angular cutaway portions 1l).

'13 v"designates the metal 'roofing which I comprises a plurality ofmetal sections 14.` 25

Each-section 1s provided with an upturned Vfian e of double thickness, upon one side,

whi e the other side is alsoprovided with an 'upxturned -lange 16l of double thickness, but w '30 `ich is curved uponitself, as shown at 17,

in order to form-a downwardly extending 'flange 18,- between which and the flange 16 i' the flange 15 is loosely. arranged, in ordei` to allow the various metalsections tohave a slight play, in case the structure ofthe car is slightl distorted, whichmay b edue to unavoidab eaccidents. One of the thicknesses'fforming the flange 16 .is bent at right angles, as at 19, in orderto form'the flange .l 20, .wliich'is disposed beneath a portion of 40 the adjacent section of the metal roofing,.as

" shown clearly in Fig. 8 of the drawings,

.The various sections. of the metal roofing 'Y are provided with upwardly curved or rolle portions. 2.1,l which `are arranged adjacent the longitudinal raised portion ofthe rid epole, over which andthe loose joints eytween` the'various sections, the cap plate,

i coveror closure 22 is. positioned. This cap' plate 4or coveris provided with laterally ex: v tending portions 23l forming recesses 24,

- which .receive the loose joints betweenthe saddles rest uponA t adapted to support the running boards '28, There are a .plurality v ofsaddles or supports shown, and at various locations,- 4which are' ated by the character 29.- .'Two-of the, sad les are shown as being-bolted together. A

and are provided with upwardly projecting port-ions 3 2 and .flanges 33. lThese flanges engage opposite sides of the saddles. The upwar hollowed out, as shown at 34, from the under. faces of the holding members, in order to receive the heads lof -the boltsl 1y .projecting portions 32 are.

The openings 37 of the Vhfol'lowed .out i portions are provided with restricted por-j tions `38, in which the Shanks 'oft the bolts are disposed, while the heads of the bolts engage shoulders 39,' for instance, when the bolts are centrallydisposed with regard to the holding members. The openings to the liollowed out portions ofthe holding members are also shaped, as at 40, in order to admit the heads of the. bolts, when assemblingthevarious parts.` Theseboltspenetrate through every other saddle of the struct-ure of the upper portion of the car, and the ridge-pole, and u on their lower extremities, nuts 41 are threa ed,
